Singh will also file a complaint against Mayawati with the Election Commission on January 30. Mayawati, had on January 26 announced that four-time MLA Ansari, will contest the Uttar Pradesh elections from the Mau assembly constituency on BSP ticket while asserting that the latter is being taken back in the party as the allegations against him have not been proved yet.
The gangster-turned-politician's son Abbas and brother Sibgatulla have also joined the party and they will be contesting the elections from Ghosi and Mohammadabad assembly constituencies respectively. The MLA had earlier won a seat from Mau in 1996 on a BSP ticket.
Ansari, who is currently lodged in Lucknow jail, was the prime accused in the Krishnanand Rai murder case, and has pleaded not guilty. In 2010, Ansari was also booked for the murder of Ram Singh Maurya, who was a witness to the murder of Manna Singh.
